I am booked to take the physics gre exam in October. I want to shift the datge of my exam to November. Can I do this online?What are the procedures?? I know the fee is $50.

The reason I want to do this is because there are not a lot of colleges which admit students for MS-PhD in the January session - So my best chances are in next Fall - which means that I best defer the exam by a month and write a better test in November.

So please let me know the procedure if anyone of you know it - I would prefer to do it online as opposed to by mail.
